This article will explain in detail what the format of the switch sentence is. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The format of the switch statement is [switch (expression) {case value 1: statement body 1: Breaking case value 2: statement body 2: statement body 2;]; where breaktable indicates the meaning of break, and when all values do not match, the statement body default is executed.

The format of the switch statement is:

1. Switch statement format:

Switch (expression) {case value 1: statement aspect 1; break; case value 2: statement aspect 2; break;. Default: sentence body nasty 1; break;}

2. Format explanation:

Expression: byte,short,int,char

The value after case: is what is used to match the value of the expression

Break: the meaning of table break

Default: when all the values do not match, execute the statement body default

3. Execution process:

A: first evaluate the value of the expression

B: compare the calculated value with the value after case in turn. Once there is a match, the corresponding statement is executed and ends when break is encountered.

C: if all the case do not match, execute the body of the statement

4. Example code:

Scanner sc= new Scanner (System.in); System.out.println ("Please enter the number 1-7"); int I = sc.nextInt () Switch (I) {case 1: System.out.println (Monday); break Case 2: System.out.println (Tuesday); break; case 3: System.out.println (Wednesday); break Case 4: System.out.println (Thursday); break; case 5: System.out.println (Friday); break Case 6: System.out.println (Saturday); break; case 7: System.out.println (Sunday 1); break Default: System.out.println ("Please enter the correct number:"); break; on how the format of the switch sentence is shared here, I hope the above content can be of some help to you, can learn more knowledge.
